【摘要】：缠绕式超深矿井提升机钢丝绳出绳型式的确定对于矿井提升机主轴及其系统安全可靠运行具有重要作用。针对钢丝绳出绳型式对主轴承载优劣的问题,通过建立力学模型、数值计算与有限元分析相结合的方法推导了主轴变载荷计算通式,编写了16种工况的数值计算程序并进行仿真计算,由此比较提出了钢丝绳的最佳出绳型式。研究表明:提出的主轴变载荷计算通式对于16种工况下提升(或下放)时左、右卷筒都适用;采用S曲线速度或多阶段速度运行有利于主轴运行的稳定性;腹板对称或非对称(L_8,L_(10)差值150 mm以内)时,游筒两绳区左、下出绳,固筒两绳区右、上出绳为最佳出绳型式。研究方法和成果有利于确定主轴受载情况,对于设计主轴以及确定超深矿井提升机的出绳型式可提供理论参考。
[Abstract]:The determination of wire rope type of winding type super deep mine hoist plays an important role in the safe and reliable operation of mine hoist spindle and its system. In view of the problem that the rope type of wire rope is good or bad to the bearing capacity of spindle, the general formula for calculating variable load of spindle is derived by establishing mechanical model, combining numerical calculation with finite element analysis. The numerical calculation program of 16 working conditions is compiled and simulated, and the optimum type of wire rope is compared and put forward. The results show that the general formula for calculating the variable load of the spindle is applicable to both the left and right reels when lifting (or lowering) under 16 working conditions, and that the S-curve speed or multi-stage speed operation is beneficial to the stability of the spindle operation. When the web is symmetrical or asymmetrical, the difference is less than 150 mm). The research methods and results are helpful to determine the load of the main shaft and provide a theoretical reference for the design of the spindle and the determination of the rope type of the super deep mine hoist.
